I redid your calculations,
I redid your calculations, including the cost of oil, and the cost of DEF, which works out to only a penny a mile. Making the new cost per mile of 86 cents. ($0.86)
I understand you said Tesla can provide, but nobody's going to believe that, including me, so I figured the calculations based on the average kilowatt hour price in the US of 12 and 1/2 cents ($0.12⁵)
200 mi * 12.5¢ = $25, which is still less than 1/3 the cost of driving the semi. That is a more believable number.
